Acrylic fibers are synthetic fibers made from a polymer called polyacrylonitrile. They are known for their lightweight, soft texture and are often used as a substitute for wool in clothing and textiles. Acrylic fibers are resistant to moths, mildew, and sunlight, making them a popular choice for outdoor fabrics and garments. These fibers can be easily dyed and retain color well, which enhances their appeal in fashion and home décor. Common products made from acrylic fibers include sweaters, blankets, and carpets. Their versatility and affordability contribute to their widespread use in the textile industry.
